STUDIES ON THE ISOHYDRIC POINT. XIX. THE HYDRATED GERMANIUM OXIDES GEO2.XH2O.AQ. (PREPARATION, THERMOGRAVIMETRY, X-RAYS),
Abstract
Specifications are given for the preparation of crystalline samples of GeO2 containing different amounts of water, the sample richest in water containing 5% of the latter. The simultaneously performed study by means of thermobalance and X rays shows that while in the case of the different samples the hexagonal crystal lattice of the socalled 'soluble' form of GeO2 remains the same at all temperatures, the water of hydration may be clearly classified into two distinct categories: (1) weakly bound and reversible; this water leaves the oxide at low temperatures and may be legitimately considered as being simply adsorbed (or absorbed); and (2) firmly bound and irreversible.
